Comment 10 for bug 1873960

@freyes I ran this by the team in a hangout ... and got a little bit of pushback :-)

What charms, specifically, are failing in the absence of swap? Are they working on AWS? And what are/how terrible are the workarounds?

I know that there are some circumstances where, for example, a golang program will try to over commit on memory, and the kernel will refuse to do so if the machine doesn't have swap enabled. But it seems like this would be biting us on other clouds if there weren't already decent workarounds in the charms ...
